The blind zone is the area immediately in front of the transducer where it cannot detect objects because the crystal is still vibrating after the transmit pulse.
Ultrasonic Receivers, Transmitters - Industrial Component Intelligence
Precision acoustic sensing for industrial automation and process control.
What are Ultrasonic Receivers, Transmitters - Industrial components?
Industrial ultrasonic sensors use high-frequency sound waves to detect objects or measure distances regardless of color, transparency, or surface finish. Selection hinges on operating frequency, detection range, beam angle, and environmental sealing (IP rating).
How to Choose Ultrasonic Receivers, Transmitters - Industrial Components
Selecting the right transducer requires balancing physical constraints with environmental demands.
Operating Frequency
Lower frequencies (e.g., 40kHz) offer longer range; higher frequencies provide better resolution for small objects.
Detection Range
Define the 'blind zone' and maximum detection distance to ensure the sensor covers your specific workspace.
Environmental Sealing
Verify IP ratings (e.g., IP67/68) if the sensor will be exposed to dust, moisture, or chemical washdowns.
Beam Angle
Narrow beams are ideal for precise point detection, while wide beams are better for area monitoring.
Output Interface
Choose between analog (0-10V, 4-20mA) or digital (IO-Link, switching) interfaces based on your PLC architecture.
